Patent number: 11837764Abstract: Methods and devices and aspects thereof for generating power using PEM fuel cell power systems comprising a rotary bed (or rotatable) reactor for hydrogen generation are disclosed. Hydrogen is generated by the hydrolysis of fuels such as lithium aluminum hydride and mixtures thereof. Water required for hydrolysis may be captured from the fuel cell exhaust. Water is preferably fed to the reactor in the form of a mist generated by an atomizer. An exemplary 750 We-h, 400 We PEM fuel cell power system may be characterized by a specific energy of about 550 We-h/kg and a specific power of about 290 We/kg. Turbidity fixtures within the reactor increase turbidity of fuel pellets within the reactor and improve the energy density of the system.Type: GrantFiled: March 4, 2020Date of Patent: December 5, 2023Assignee: Intelligent Energy Inc.Inventors: Jason L. Stimits, Russell Barton, Douglas A. Knight, Iain M. Fraser, Hao Huang, Sandra H. Withers-Kirby, Philbert C. Spencer, Piotr Marcin Kleszyk, Hossein Ostadi

Patent number: 6470982Abstract: A children's ride-on vehicle with a reduced scale chassis having a seat configured to accommodate at least one child. The vehicle further includes a drive assembly, which includes one or more drive wheels and a battery powered motor assembly. The battery powered motor assembly includes a motor output and a torque attenuation system, which is configured to regulate the transmission of torque from the motor assembly to the one or more drive wheels. The torque attenuation system incorporates a force reducing mechanism adapted to receive a rotational input from the motor output and regulate the transmission of that rotational input to the one or more drive wheels. In some embodiments of the invention, the torque attenuation system is a self-contained system, and in some embodiments of the invention, the torque attenuation system is adapted to be retrofit on existing children's ride-on vehicles.Type: GrantFiled: February 8, 2001Date of Patent: October 29, 2002Assignee: Mattel, Inc.Inventors: Gerald P. Sitarski, Daniel Dignitti, Steven Robert Drosendahl, Walter C. Miazga, Douglas A. Knight
